Sovereign debt troubles in Europe underscore how important it is for the United States to control its own borrowing as its indebtedness reaches concerning levels, a senior Chinese official said. With China facing criticism for holding its currency in

Previously, artificial skin has been made from biomaterials such as collagen, polyglycolic acid, and chitosan. The fibrin-agarose skin, however, looks particularly promising. Prof. Jiménez Rodríguez, one of the researchers, stated "Definitively, we

Firstly, the D-Drive as pictured in our video is not a complete infinitely variable transmission system. At best, according to the engineering report, it is a cheap, innovative and potentially very useful primary component of an IVT.

Substation automation is not just about making an individual point smarter, but empowering communications across the grid. "The paradigm shift is that no longer is it simply, 'if this happens, switch this,'" said Wes Sylvester, the Director of Sm

Mr. Myhrvold played a slow-motion recorded video that showed what happened to a representative mosquito. As the insect flew, a sudden light beam struck it, disintegrating parts of its body into a plume of smoke. It fell, even as its wings continued t

From left, Jeffrey Long, Christopher Chang and Hemamala Karunadasa have discovered an inexpensive metal that can generate hydrogen from neutral water, even if it is dirty, and can operate in sea water. (Credit: Photo by Roy Kaltschmidt, Berkeley Lab

"The whiskers, feet, and scales of the dragon were above the water, and the dragon was several dozens of meters long." The dragon might have appeared more than once around Mount Long and Lake Yilong, thus explaining the choice of names for these pl

"Those of us who live outside Africa carry a little Neanderthal DNA in us," Pääbo says. The study estimates that between 1 and 4 percent of non-African DNA is inherited from these long-ago liaisons with our Neanderthal cousins.

Low vitamin D levels have long been linked to a higher risk of MS. Experts suspect an expectant mother's lack of exposure to sunlight - the main source of vitamin D - may affect the fetus's central nervous system or immune system, and predispose it

Mammoths had a form of "anti-freeze" blood to keep their bodies supplied with oxygen at freezing temperatures. Nature Genetics reports that scientists "resurrected" a woolly mammoth blood protein to come to their finding.

The scope of the government’s involvement in bioweapons research, may be gauged from its estimated expenditure of $70 billion since 9/11 and the fact that, according to Ebright, more than 400 U.S. institutions are engaged in such work.

"The current carries dense, oxygen-rich water that sinks near Antarctica to the deep ocean basins further north," says co-author Dr Steve Rintoul from the Antarctic Climate and Ecosystems CRC and CSIRO's Wealth from Oceans Flagship.

allowing for the development of broadband wide-angle metamaterials that could enhance light collection in solar cells," he explains. "And the fact that the metamaterial has a wide-angle response is important because it means that it can 'accept'

Russia’s National Assoc. for Gene Security and the Institute of Ecological and Evolutional Problems has revealed that hamsters fed genetically modified (GM) foods produce grandchildren that are unable to produce fourth generation offspring.

Their results suggest that it will soon be possible to control plasmons, i.e. collective oscillations of electrons, purposefully in the graphene, by virtually establishing a lane composed of projections and humps for them. The results were published

Stacked layers of oxidized graphene could be used to store hydrogen fuel for cars and other applications. So say researchers in the US who have made graphene-oxide frameworks (GOFs) that can hold roughly 1% of their weight in hydrogen. This value is

So how much smaller, faster and cheaper can computers go? Lots, if graphene, the nanomaterial of the new millennium, has anything to say about that.
Discovered just a few years ago, graphene is only the thickness of one atom but it scores on str

The answer was within the next year or two. But today GE announced that they'll have an LED bulb replacement using Cree's LEDs available by the end of 2010. Now, let's be clear, this joint project from Cree and GE isn't as bright or as technologi
